Wile E. Coyote (Carnivorus hungribilus) is chasing the Roadrunner (Speedibus cantcatchmi) yet again. While running down the road, they come to a deep gorge, 14.4 m straight across and 100 m deep. The Roadrunner launches himself across the gorge at a launch angle of 16° above the horizontal, and lands with 1.4 m to spare.
(a) What was the Roadrunner's launch speed?
(b) Wile E. Coyote launches himself across the gorge with the same initial speed, but at a different launch angle. To his horror, he is short of the other lip by 0.50 m. What was his launch angle? (Assume that it was less than 16°.)
